Fixed three-course menus deliver predictable margins while à la carte pricing creates revenue uncertainty. Your guests control spending patterns with individual dish selection - some pick expensive items (lower margins), others choose budget-friendly options (higher margins). Fixed menus let you control exactly what each guest costs.
The difference in margin structure
With à la carte, guests drive their own spending patterns. Some pick expensive dishes that squeeze your margins, others gravitate toward cheaper options that boost profitability. Fixed three-course menus eliminate this guesswork - you know precisely what each guest costs before they sit down.
💡 Example fixed menu:
Three-course menu for €45.00 incl. VAT (€41.28 excl.):
- Starter: €3.20 ingredients
- Main course: €8.50 ingredients
- Dessert: €2.10 ingredients
Total food cost: €13.80 = 33.4%
Calculate average margin with à la carte
You'll need to crunch your till data from the past month. Pull these numbers together:
- Total covers (guests served)
- Food revenue (excluding drinks and VAT)
- Your top-performing dishes by order frequency
💡 Example à la carte:
1000 guests, €38,500 food revenue excl. VAT:
- Average spending: €38.50 per guest
- Most popular starter (60%): €7.50 - food cost €2.80
- Most popular main course (40%): €24.50 - food cost €9.20
- Dessert (30%): €8.50 - food cost €2.40
Weighted average food cost: approximately 35.8%
The calculation per system
Fair comparison means using identical timeframes. Let's work with 1000 guests monthly.
Fixed menu calculation:
1000 guests × €41.28 excl. VAT = €41,280 revenue
1000 guests × €13.80 food cost = €13,800 ingredients
Gross margin: €41,280 - €13,800 = €27,480
À la carte calculation:
1000 guests × €38.50 excl. VAT = €38,500 revenue
€38,500 × 35.8% food cost = €13,783 ingredients
Gross margin: €38,500 - €13,783 = €24,717
⚠️ Note:
This assumes you can charge the same price for fixed menus as average à la carte spending. Reality often differs - guests typically accept slightly higher prices for fixed menus since they don't need to make decisions.
Include operational advantages
Fixed menus create operational efficiencies you can quantify:
- Purchasing: You buy exactly what you need, dramatically reducing waste
- Preparation: Streamlined mise-en-place, fewer dishes to prep
- Staff: Faster service times, fewer kitchen mistakes
After managing kitchen operations for nearly a decade, I've seen these savings range from 2-5% of total costs. With €41,280 revenue, that's €800-2000 monthly savings.
Deciding which system maximizes profit
Fixed menus win financially if:
- You can price higher than average à la carte spending
- You capture operational savings (reduced waste, efficient purchasing)
- You design low-cost, high-impact ingredient combinations
À la carte works better if:
- Guests consistently spend more than fixed menu pricing
- Your high-margin dishes dominate orders
- You prioritize flexibility over maximum margin control
✨ Pro tip:
Run a 6-week split test - fixed menu for 3 weeks, then à la carte for 3 weeks. Track food cost percentages, average check sizes, and kitchen ticket times to determine your most profitable approach.
How do you calculate the margin impact? (step by step)
Collect till data from à la carte period
Get one month of data: number of guests, total food revenue excl. VAT, and which dishes were most popular. Calculate the average spending per guest by dividing revenue by number of guests.
Calculate weighted average food cost à la carte
Add up per popular dish: (popularity % × food cost of that dish). Sum all dishes for your total weighted food cost percentage.
Design fixed three-course menu and calculate exact food cost
Choose starter, main course and dessert. Add up all ingredient costs. Divide by desired selling price excl. VAT for your food cost percentage.
Compare gross margins based on same number of guests
Calculate both scenarios for example 1000 guests. Subtract ingredient costs from revenue for your gross margin. The difference shows you the margin impact.

Frequently asked questions
Should I include VAT in the margin calculation?
No, always calculate with prices excluding VAT. VAT is a pass-through item that you remit to tax authorities. Only your net receipts matter for margin calculations.
How do I determine the price of a fixed three-course menu?
Start with your target food cost percentage (typically 30%) and calculate: total ingredient costs divided by 0.30. Compare this with average à la carte spending and adjust accordingly.
What if guests spend less with a fixed menu?
Factor in operational advantages like reduced waste and streamlined purchasing. You can also increase menu pricing slightly since guests value the convenience of not choosing.
How often should I update this calculation?
Review every 3 months to ensure your assumptions remain accurate. Ingredient prices fluctuate, and à la carte dish popularity shifts over time.
Can I combine both systems?
Absolutely - try fixed menus on weekdays and à la carte on weekends. Calculate margin impact separately for each period to optimize your approach.
What food cost percentage should I target for each system?
Fixed menus typically run 28-32% food cost due to better portion control. À la carte often ranges 32-38% because of varying guest choices and potential waste.
